Directives¶
Directives are the configuration option of PHP. They may be set in the php.ini file, in HTTP server files like .htaccess, or accessed via the ini_get() and ini_set() native calls.
Directives are also set by PHP extensions or by PHP applications.
<?php
echo 'display_errors = ' . ini_get('display_errors') . "\n";
echo 'register_globals = ' . ini_get('register_globals') . "\n";
echo 'post_max_size = ' . ini_get('post_max_size') . "\n";
echo 'post_max_size+1 = ' . (ini_get('post_max_size')+1) . "\n";
echo 'post_max_size in bytes = ' . return_bytes(ini_get('post_max_size'));
?>
